Question

我遇到Ruby 2.0和rails 4.0的问题。

我有一个form_for创建一个新的“项目”条目，其中包含标题，描述和状态。形式本身曾经像魅力一样工作，直到我做了一些事情，我不知道是什么。问题是，表单渲染完美，但在向其添加VALID值并按下提交按钮后，它什么都不做。如果我在输入值和提交之前刷新表单，则网址会更改为：

项目/新UTF8 =✓＆安培; authenticity_token = Xh6ZGV2vvth1RzhBk3g5zonms％2Fdq3yzaJtzxDU％2FFBiM％3D＆安培;项目％5Btitle％5D =项目+标题＆安培;项目％5Bdescription％5D =描述＆安培;项目％5Bstatus％5D =正在进行＆安培;提交=提交

奇怪的是，如果我在同一个文件中第一个之后添加另一个完全相同的表单，那么第二个表单就可以完美运行。

我的项目new.html.erb

<h1>Create a new project</h1>
<div class="row">
  <div class="col-md-5">
    <%= form_for @project do |f| %>
        <%= f.label :title %>
      <%= f.text_field :title %>
      <%= f.label :description %>
      <%= f.text_field :description %>
      <%= f.label :status %>
      <%= f.select :status, [['Ongoing', 'Ongoing'],['Suspended','Suspended'],['Finished','Finished']] %>
      <%= f.submit "Submit" %>
    <% end %>
  </div>
</div>

projects_controller.erb

  def new
      @project = Project.new
  end

  def create
    @project = Project.new(project_params)
    if @project.save
      flash[:success] = "Project successfully created!"
      redirect_to root_path
    else
      render 'new'
    end
  end

  private

  def project_params
    params.require(:project).permit(:title, :description, :status)
  end

正如我所说的那样，之前曾经没有问题。此外，我试图禁用JS，但它仍然无法正常工作。如果您对问题有任何想法，请告诉我。谢谢。

编辑：

从new.html.erb生成的HTML

<div class="container">

      <h1>Create a new project</h1>
<div class="row">
  <div class="col-md-5">
    <form accept-charset="UTF-8" action="/projects" class="new_project" id="new_project" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="&#x2713;" /><input name="authenticity_token" type="hidden" value="Xh6ZGV2vvth1RzhBk3g5zonms/dq3yzaJtzxDU/FBiM=" /></div>
      <label for="project_title">Title</label>
      <input id="project_title" name="project[title]" type="text" />
      <label for="project_description">Description</label>
      <input id="project_description" name="project[description]" type="text" />
      <label for="project_status">Status</label>
      <select id="project_status" name="project[status]"><option value="Ongoing">Ongoing</option>
<option value="Suspended">Suspended</option>
<option value="Finished">Finished</option></select>
      <input name="commit" type="submit" value="Submit" />
</form>  </div>
</div>

    </div>

提交表单后添加日志：

Answer 1

我认为这不是来自rails，可能是您的浏览器的扩展，例如开发人员工具，或者可能是您的Web服务器的配置

尝试使用其他浏览器访问您的表单，最好是没有或只有少量扩展程序
如果它不起作用，请使用firebug并在Net标签中看到如果您在提交后从POST重定向到GET请求
使用其他网络服务器，切换到webrick，thin，puma或其他任何内容并查看

Rails form_for没有做任何事情
